[0032] By placing the medicine bottle into the first rotating sleeve 3, and then fixing the top of the medicine bottle by the first clamping assembly 5, and fixing the bottom of the medicine bottle by the second clamping assembly 6, and then starting the driving mechanism 7 to drive the swing frame 2 to swing back and forth, the first rotating sleeve 3 and the second rotating sleeve 4 follow the swing frame 2 to swing back and forth for shaking, and at the same time, the transmission mechanism 8 cooperates with the swinging of the swing frame 2 to drive the second rotating sleeve 4 to rotate back and forth, so that the medicine bottle follows the second rotating sleeve 4 to rotate back and forth, so that the medicine bottle rotates while swinging, so that the medicine liquid inside the medicine bottle flows in multiple directions for sufficient mixing, which greatly improves the mixing effect of the medicine liquid inside the medicine bottle.

[0033] Furthermore, the first clamping assembly 5 includes a plurality of sliding rods 51 penetrating the side wall of the first rotating sleeve 3, the plurality of sliding rods 51 are slidably connected to the side wall of the first rotating sleeve 3, and the plurality of sliding rods 51 are equally distributed around the first rotating sleeve 3, one end of the plurality of sliding rods 51 is fixedly connected to a clamping plate 52, the other end of the plurality of sliding rods 51 is fixedly connected to a pull block 53, a plurality of sliding rods 51 are sleeved with a spring 54, one end of the plurality of springs 54 is in contact with the corresponding clamping plate 52, and the other end of the plurality of springs 54 is in contact with the inner wall of the first rotating sleeve 3.

[0034] By pulling one of the pull blocks 53, the slide bar 51 slides toward the outside of the first rotating sleeve 3, so that the clamping plate 52 approaches the side wall of the first rotating sleeve 3. At this time, the spring 54 is compressed to accumulate potential energy, which makes it convenient to put the medicine bottle on the inside of the first rotating sleeve 3. Then, the pull block 53 is released to release the potential energy of the spring 54, so that the clamping plate 52 moves in the opposite direction to clamp and fix the medicine bottle, thereby ensuring that the top of the medicine bottle remains stable.

[0035] Furthermore, the second clamping assembly 6 includes a support seat 61 for supporting the bottom of the medicine bottle, the support seat 61 is slidably connected to the inner side of the second rotating sleeve 4, the outer edge of the support seat 61 is fixedly connected to a number of movable plates 62 distributed at equal angles around the support seat 61, the movable plates 62 all penetrate the side walls of the second rotating sleeve 4, and a number of movable plates 62 are slidably connected to the second rotating sleeve 4, a number of cylinders 63 corresponding to the movable plates 62 are fixedly connected to the bottom end of the outer side of the second rotating sleeve 4, the output ends of the cylinders 63 are fixedly connected to the corresponding movable plates 62, the outer wall of the second rotating sleeve 4 is provided with a number of slide grooves 64 corresponding to the movable plates 62 in the vertical direction, a number of movable plates 62 are slidably connected to the inner walls of the corresponding slide grooves 64, and a clamping member 65 for fixing the bottom end of the medicine bottle is provided on the inner side of the support seat 61.

[0036] By setting up a support seat 61, the bottom of the medicine bottle can be supported, so as to avoid the problem of the medicine bottle being offset and separated from the clamp 52 during the shaking process. By controlling the cylinder 63 to drive the movable plate 62 to slide along the slide groove 64, the support seat 61 can slide on the inner side of the second rotating sleeve 4. In this way, the position of the support seat 61 can be adjusted according to the length of the medicine bottle, so that the support seat 61 can support the bottom of medicine bottles of different lengths to ensure that the medicine bottle remains stable during the shaking process.

[0037] Furthermore, the clamping member 65 includes a plurality of sliding rods 651 penetrating the inner wall of the support seat 61, the plurality of sliding rods 651 are slidably connected to the inner wall of the support seat 61, and the plurality of sliding rods 651 are equally distributed around the support seat 61, one end of the plurality of sliding rods 651 is fixedly connected to a clamp plate 652, the other end of the plurality of sliding rods 651 is fixedly connected to a pull block 653, a plurality of sliding rods 651 are sleeved with a spring 654, one end of the plurality of springs 654 is in contact with the corresponding clamp plate 652, and the other end of the plurality of springs 654 is in contact with the inner wall of the support seat 61.

[0038] By pulling one of the pull blocks 653, the slide rod 651 slides toward the outside of the support seat 61, causing the splint 652 to approach the inner wall of the support seat 61. At this time, the spring 654 is compressed to accumulate potential energy, and then the bottom end of the medicine bottle can be placed inside the support seat 61. The pull block 653 is then released to release the potential energy of the spring 654, causing the splint 652 to move in the opposite direction and clamp the bottom end of the medicine, further improving the stability of the medicine bottle.

[0039] Furthermore, the driving mechanism 7 includes a swing rod 71 coaxially fixedly connected to the swing frame 2, a bracket 72 is fixedly connected to the outer side of the frame 1, a motor 73 is fixedly installed on the top of the bracket 72, an eccentric wheel 74 is fixedly connected to the output shaft of the motor 73, a connecting rod 75 is rotatably connected to the outer edge of the eccentric wheel 74, and a connecting piece 76 rotatably connected to the connecting rod 75 is provided on the swing rod 71.

[0040] By starting the motor 73, the eccentric wheel 74 is driven to rotate, so that the connecting rod 75 drives the swing rod 71 to swing back and forth. Since the swing rod 71 is coaxially fixedly connected to the swing frame 2, the swing frame 2 will swing back and forth synchronously, so that the first rotating sleeve 3 and the second rotating sleeve 4 follow the swing frame 2 to swing back and forth to perform the shaking work.

[0041] Furthermore, the connecting member 76 includes a slider 761 that passes through the swing rod 71, the slider 761 is rotatably connected to the connecting rod 75, and a guide groove 762 that is slidably connected to the slider 761 is provided on the swing rod 71. One side of the guide groove 762 is provided with a plurality of sockets 764 that are equidistantly distributed along the length direction of the guide groove 762, and one end of the slider 761 is connected to a pin 763 that slidably cooperates with one of the sockets 764.

[0042] By pulling out the pin 763, the slider 761 can slide along the guide groove 762. After determining the position, the pin 763 can be reinserted to adjust the connection position between the connecting rod 75 and the swing rod 71, and the swing angle of the swing rod 71 can be adjusted. In this way, the swing angle of the first rotating sleeve 3 and the second rotating sleeve 4 can be adjusted, and then the shaking amplitude of the medicine bottle can be adjusted according to the actual shaking requirement of the amount of medicine liquid in the medicine bottle, so that the medicine liquid can be fully shaken.

[0043] Furthermore, the transmission mechanism 8 includes a bevel gear 81, which is fixedly connected to the bottom of the second rotating sleeve 4. The bottom end of the swing frame 2 is rotatably connected to a bevel gear 82 meshing with the bevel gear 81. One side of the bevel gear 82 is coaxially fixedly connected to a transmission gear 83. The bottom end of the frame 1 is fixedly connected to a mounting plate 84, one side of the mounting plate 84 is fixedly connected to an arc-shaped tooth plate 85, and the transmission gear 83 meshes with the arc-shaped tooth plate 85.

[0044] Working principle: First, by pulling one of the pull blocks 1 53, the slide bar 1 51 slides toward the outside of the first rotating sleeve 3, so that the clamping plate 1 52 approaches the side wall of the first rotating sleeve 3. At this time, the spring 1 54 is compressed and accumulates potential energy, so that the medicine bottle can be easily placed on the inner side of the first rotating sleeve 3. Then, one of the pull blocks 2 653 is pulled to make the slide bar 2 651 slide toward the outside of the support seat 61, so that the clamping plate 2 652 approaches the inner wall of the support seat 61. At this time, the spring 2 654 is compressed and accumulates potential energy. Then, the bottom end of the medicine bottle can be placed on the inner side of the support seat 61. Then, the pull block 1 53 is released to make the spring 1 54 release the potential energy, so that the clamping plate 1 52 moves in the opposite direction to clamp and fix the medicine bottle. At the same time, the pull block 2 653 is released to make the spring 2 654 release the potential energy to make the clamping plate 2 652 move in the opposite direction and clamp the bottom end of the medicine, thereby further improving the stability of the medicine bottle.

[0045] The support seat 61 can be provided to support the bottom of the medicine bottle, so that the problem of the medicine bottle being offset and separated from the clamping plate 52 during the shaking process can be avoided. The movable plate 62 is driven to slide along the slide groove 64 by controlling the air cylinder 63, so that the support seat 61 slides on the inner side of the second rotating sleeve 4. In this way, the position of the support seat 61 can be adjusted according to the length of the medicine bottle, so that the support seat 61 can support the bottom of medicine bottles of different lengths to ensure that the medicine bottle remains stable during the shaking process;

[0046] When it is necessary to shake evenly, the eccentric wheel 74 is driven to rotate by starting the motor 73, so that the connecting rod 75 drives the swing rod 71 to swing back and forth. Since the swing rod 71 is coaxially fixedly connected with the swing frame 2, the swing frame 2 will swing back and forth synchronously, so that the first rotating sleeve 3 and the second rotating sleeve 4 follow the swing frame 2 to swing back and forth to shake evenly;

[0047] During the swinging process of the swing frame 2, the transmission gear 83 will roll back and forth along the arc-shaped tooth plate 85, so that the bevel gear 2 82 rotates synchronously, and the bevel gear 1 81 drives the second rotating sleeve 4 to rotate, and the first rotating sleeve 3 drives the medicine bottle to rotate. In this way, the medicine bottle rotates while swinging, and the medicine liquid inside the medicine bottle flows in multiple directions for full mixing, which greatly improves the mixing effect of the medicine liquid inside the medicine bottle.

[0048] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
